The world of luxury watches is dominated by a handful of powerhouse brands, and among them, Omega and Rolex consistently vie for the top spot. A significant factor in this competition lies within the movements powering their timepieces: the Omega 8500 and the Rolex 3135. Both are renowned for their reliability and performance, but understanding their nuances, strengths, and potential weaknesses is crucial for any discerning watch enthusiast. This article will provide an in-depth comparison of these two iconic movements, addressing common concerns and analyzing their respective merits. We will delve into reported issues, design philosophies, and ultimately help you understand which movement might be better suited to your needs and preferences.
The Omega 8500: Co-Axial Innovation and Modern Design
The Omega 8500 is a self-winding, automatic movement that represents a significant step forward in Omega's horological evolution. Its defining characteristic is the incorporation of Omega's Co-Axial escapement, a technology designed to reduce friction and increase longevity compared to traditional lever escapements. This innovative feature promises improved accuracy and longer service intervals between servicing. The 8500 boasts a silicon balance spring, further enhancing its resistance to magnetic fields and shocks. This combination of advanced materials and design contributes to its claimed superior performance.
Beyond the Co-Axial escapement, the 8500 features a free-sprung balance, allowing for greater accuracy and stability. It also incorporates a column-wheel chronograph mechanism in its chronograph variants (e.g., 8500/9500 family), adding another layer of sophistication. The movement is visually appealing, often featuring meticulously finished components visible through display casebacks. This transparency allows owners to appreciate the craftsmanship and engineering that goes into the movement. The power reserve typically sits around 55 hours, providing ample running time.
Omega 8500 Problems: Addressing Reported Issues
While the Omega 8500 is generally considered a robust and reliable movement, like any mechanical device, it's not immune to potential problems. Online forums often discuss certain recurring issues, though it's crucial to remember that these represent a small fraction of the total number of 8500 movements produced. The reported problems are often anecdotal and may stem from various factors, including individual watch handling, environmental conditions, and even manufacturing variations.
Some of the reported Omega 8500 problems and Omega Co-Axial 8500 problems frequently discussed include:
* Magnetism: While the silicon balance spring offers significant resistance to magnetism, it's not entirely immune. Exposure to strong magnetic fields can still affect the movement's performance. This is less a fault of the movement itself and more a consequence of the environment.
* Service Intervals: While Omega claims extended service intervals, the actual frequency of servicing can vary depending on usage and environmental factors. Some owners have reported needing service sooner than anticipated. This is a common issue with all mechanical watches, however, and not necessarily indicative of a flaw in the 8500 itself.
